To detect contact at all positions to prevent cracks and damage due to contact.SOLUTION: A contact detection sensor 10 comprises a base film 11, a plurality of electrodes 12... arranged on one surface thereof at predetermined intervals in the longitudinal direction of a member, wirings 14... arranged on the other surface of the base film 11 and electrically connected to the electrodes 12 via through holes 13, and a conductive member 15 that extends in the longitudinal direction of the member of the base film 11 and is arranged so as to be separated from the electrode 12 and in contact with the electrode 12. When under pressure, the contact can be detected when the conductive members 15 come into contact with each other across the adjacent electrodes 12, the electrodes 12 conduct with the conductive members 15, and the wirings 14 connected to the electrodes 12 conduct with each other.SELECTED DRAWING: Figure 8 【課題】全ての位置で接触が検知でき、接触によるクラックの発生や破損を防止する。【解決手段】接触検知センサ１０は、ベースフィルム１１と、その一方面に部材長手方向に所定の間隔で複数配置された電極１２...と、前記ベースフィルム１１の他方面に配置されるとともに、スルーホール１３を介して電極１２に電気的に接続された配線１４...と、ベースフィルム１１の部材長手方向に沿って延び、電極１２から離隔するとともに電極１２に接触可能に配置された導電部材１５とを備える。圧力を受けた際、導電部材１５が隣り合う電極１２に跨がって接触し、これら電極１２が導電部材１５を介して導通するとともに、これら電極１２に接続する配線１４が導通することによって、接触が検知できる。【選択図】図８
